Abstract CHARACTERIZING PATTERNS AND DRIVERS OF LAND USE/LAND COVER CHANGE ALONG THE ATLANTIC COAST BARRIER BEACHES: EXAMINING THE ROLES OF DEVELOPMENT PRESSURE, SPATIAL ACCESSIBILITY, AND POLICY By Andrew T. Bennett April 2013 Director of Dissertation: Thomas W. Crawford Major Department: Coastal Resources Management Ph.D. Program The coastal environment is an ever-changing multifaceted region that continues to evolve from natural processes as well as anthropogenic inputs over time. The purpose of this research is to create a better understanding of the coastal environment of the United States; more specifically the social and physical landscapes of Atlantic coast barrier beaches. In doing so it will move towards a science of U.S. coastal land cover change science. This is important because human land behaviors on the coast have important effects on both natural and cultural resources, terrestrial and marine environments, and regional sense of place. Because of this explicitly coastal-themed research is needed to understand the patterns and drivers of coastal landscape change in ways that integrate the biophysical and social science domains. This dissertation is comprised of three main parts that examine different aspects of Atlantic barrier beach land change and coastal development. Chapter 3, which is entitled “Landscapes and Land Cover Characterization of the U.S. Atlantic Barrier Coast: A Place-Based Typological Classification, 1990-2000” creates a placed based typology of barrier beach units across the Atlantic coast. Many of the U.S. Atlantic coast’s barrier beaches have undergone a shift in place identity from elite getaway destinations and small fishing communities to tourist-driven, place- based destinations. This dynamic is related to changing demographic and economic characteristics that may also be associated with changing patterns of developed land use. This chapter quantitatively examines spatial patterns of socio-economic and land use/cover characteristics for a comprehensively defined set of coastal barrier places spanning from Long Island, New York to Miami, Florida on the U.S. Atlantic coast. Census data from 1990 and 2000 and satellite derived land use/cover data are used as input to a cluster analysis generating place- based typology. Results reveal that there in fact is a separation among Atlantic Coast barrier beaches into distinct cluster types. This separation is a direct influence of the tourism industry among many of the barrier beach communities where there is large number of the housing units are seasonal units as well as lower development densities and an observed growth in developed land cover during the study period. Chapter 4, which is entitled “Rates and Drivers of Coastal Development for Atlantic Barrier Beaches” evaluates the hypothesized drivers of developed land cover change on barrier beaches. Barrier beach land use land cover has changed over time as driving forces act to shift natural barrier beach habitat to developed land cover. This is important because the important ecosystem services barrier beaches provide for the coastal region, especially along the Atlantic coast. There is little known about the forces that act upon these barrier beaches that causes developed land cover. After identifying hypothesizes of coastal driving forces of developed land use change, ordinary least squares regression (OLS) is applied. The chapter estimates five regression models that investigate natural, social, spatial, and policy variables, as well as a combination of all variables within a full model. A forward stepwise regression was also run on the full model to identify major influential factors. The results show that the full model highly explains developed land cover change on barrier beaches along the Atlantic coast and that size of a barrier beach unit over all variables is dominant factor for developed land cover change. Along with size the percent of seasonal housing were both found exhibit positive correlation to developed land cover. Chapter 5 develops a new a theoretical coastal restructuring model of land cover change. A conceptual framework of societal land use/cover change is created to aid in the creation of the historical narratives that can be applied to Atlantic barrier beach communities. The coastal restricting model is then applied to two selected Atlantic barrier beach places to interpret trajectories of development. Historical narratives are paired with quantitative results from prior chapters to guide site selection as well as provide quantitative data about each place. Using the historical narrative the phases of development are determined within the coastal restructuring model. This in turn reveals the how landscape evolves over time from one landscape use to another. The results of the analysis indicate that the coastal restructuring model has the potential to be applied to all barrier beach units as well as to be used as a guiding framework for landscape scholars and coastal planners and managers.

For that I will forever remember and continue to inspire all I can. AKNOWLEDGEMENTS I would like to give my sincere thanks to my Ph.D. degree advisor, Thomas Crawford, for guiding and encouraging me throughout this process. His guidance has made this a thoughtful and rewarding journey. His ability to select and to approach compelling research problems, high scientific standards, and hard work ethic has set an example that I will carry with me throughout my life. His enthusiasm for my work and unfailing dedication shaped this report in countless ways and often provided much needed confidence to persevere. My sincere and deepest gratitude must go to Daniel Marcucci, whose guidance and support throughout my graduate school career has been priceless. Working under his guidance over the past six years as my Masters advisor as well as on the Mid-Currituck Bridge Project has exceeded the opportunities normally bestowed on graduate students. Dan has always made time for my concerns, academic and personal alike, even at his busiest moments. He is truly a great mentor as well as a great friend. I would also like to thank the rest of my committee members, Tom Allen, Enrique Reyes, and Tracy VanHolt for their contributions to my dissertation. They have all in one way or another challenged me to go beyond my limits in creating this work. Finally, I thank all the faculty members in the Coastal Resources Management Program and the Department of Geography and Planning at East Carolina University for their helpful career advice and suggestions in general. To my family and friends your support throughout this process has enabled me to push through to my goal and will continue to motivate me into the future. To my grandparents the life lessons you have instilled in me will forever be a part of me. I know that whether you are with me or looking down on me you will always guide me to the right path. To my Parents for whom all this would have never been possible. Your support has brought me through rough times, even when others doubted me. Your own work ethics have at time made me neurotic, but never the less someone who is not afraid to put his head down and push through. The example you have set for me has shown me that anything is possible you just need to work hard and take every chance to better yourself.
